Be it known that'lgULY'ssns EL Cocina citizen ofthe UnitedStates', andiare'srdent of Pomonaf'in' the countyofFLosf Angeles'- and State ofGalifornimhave invented ceri* tain new and useful Improvements" in aPlows ofwhich the following'is a' specification. l

This-'inventionl relates toV breaking or turn'- ing plows and theprimary object of the'in vention' is to provide? a plow structure ofthis type; including an? earth-working -or' turning 'implement -or toolcarried bye a suitand also f Vtoy rocking 'the beam! to re verse theposition of the earth-workingjtool; 'Y forfconverting-fthe plow intoeitherarig'ht' -f of'clevl'sQ- attached to the' forward endof" ablerockably supportedbeam, provide meansffor handor left-hand plow i atwill.

The plow is particularlydemgned for-use upon hillsides,=loutbothdirections across a same manner that4 the ordinary" two-wayplows'are nowused. j

he supporting frame 1 has standards 15 and 16 adjustably carriedthereby, one at each side of the frame and these standards have theirlower ends angled, to form spindles which support wheels 17 and 13 relspectively. The angling of the lower spindle end of the standard 15 issuch as to position the wheels 17 and 18 at oblique angles to thevertical, as has been found desirable in plow structures of this nature.The standard 15 has a link 19 pivotally connected to its upper end whichlink is in turn pivotally connected to an arm 20. The arm '20 isprovided with a plurality of spaced openings 21 to` permit of adjustableconnection between it and the link 19. The arm 20 is mounted upon arectangular shaft 22 which extends longitudinally of the frame 1 at oneside of the same. The rectangular shaft 22 has an arm 23 mounted thereonwhich is connected by meansof a slot and pin connection as shown at 24to an arm 25. The arm 23 is formed upon the lower end of a lever 24which lever is provided for manually adjusting the standard 15independently of movement of the shaft 6 which carries the plow'. A dogmechanism is c arried by the lever 24 and co-acts with a quadrant 24ELfor locking the lever to permit it to move during the rotation off-theshaft 6. The arm 25 extends transversely of the frame 1 and has itsinner angled end 26 pivotally connected to one end of a substantiallyoval plate 27. The substantially oval-shaped plate 27 is mounted upon arectangular portion 28 of the beam 6 and forwardly of the front edge ofthe platform 4 as clearly shown in Fig. 1 of the drawings. A second armor rod 29y is connected to the end ofthe disk 27 oppositely to the endto which the rod 25 is connected. The arm 29 is connected by means of aslot and pin connection 30 to `an arm 31 carried by la rectangular shaft32. The arm upwardly from the shaft 32 and formsV a lever to permit theoperator of the standard 16 independently of operation of the shaft 6.This lever carries a dog mechanism which co-acts with a quadrant 31L tolock the lever for movement by the movement of the shaft f 6. The levers24 and 31 are provided to permit the adjustment of the wheels whencutting a first or initial furrow across a field. The rectangular shaft32 extends longitudinally along the side of the frame 1 oppositely fromthe side along which the shaft 32xextends. This shaft 32 has an arm .33mounted thereon which is adjustable and pivotally connected to the upperend of the standard 16. It will thus be seen that upon rocking movementof the beam 6 to reverse the angle and position of the land turningdisk'S, the disk 27 will also be rocked and ards and thus the 'the disk27 will 31 is elongated move the rods 25 and 29, longitudinally, whichwill in turn rock the shafts 22 and 32, imparting vertical movement tothe standards 15 and 16 through the medium of the connection between theshafts and the standrelative positions of the wheels 17 and 18 will bereversed; or in other words when the disk 8 is positioned to throw thevturned dirt to the right, the wheels 17 willv be the land wheel of theplow, riding upon the unplowed surface, Vwhile the wheel 18 will be thefurrow wheel, riding in the plowed land and when the plow is reversed,these wheels will be also reversed, raising the wheel 18, to convert itinto the land wheel and lowering the wheel 17 to/ convert it into thefurrow wheel. This movement is accomplished synchronouslywith therocking of the beam 6 as above set forth.

When the lever 10 is positioned vertically,

be arranged as illustrated in Fig. 3 of the` drawings, at whichy timethe wheels 17 and 18 will lie inthe same plane and the disk8 will beraised out of an operative position to permit transportation ofthe'plowfrom one place to another vwithout affecting the dirt or ground surfaceover which the plow is traveling. The usual type of seat 35 is supportedby the usual form of spring standard 36, from the plat- `forni 4.

From the foregoing description taken in Y connection with theaccompanying drawings, it will be readily apparent that a land breakingor turning plow has been provided which may be converted into either aright or left-hand plow, at the will of the operator and during theplowing of a field., without extensive changes, or adjustment of parts,this reversing of the positionvof thev plowing or turning elementnecesitating merely the'operation of the hand lever; thus with this plowstructure, the operator may,

It is lto be features of of the employmentof dirt may bev constructionmay be altered to suit practical conditions, without departing from the'spirit of this invention, provided such alterations are comprehendedwithin the scope of what is claimed.

What is claimed is:

1. In a turning plow, the combination of a supportingV frame, a platformcarried thereby and being of less length than the frame to provide anopening through the frame, a beam mounted to turn in the opening, a diskcarried by the beam, and means for swinging the beam to reverse theangle of the disk.

2. In a turning plow, the combination, of a supporting frame, a platformcarried by the rear portion of said frame and provided with a centrallydisposed depression, a beam rockably mounted in said depression andhaving its forward end angled and downturned, an earth-turning diskcarried by the downturned angled end of said beam and disposed in anangle to the line of travel of the plow, and means for rocking said beamto reverse the angle of said disk with respect to the line of travel ofthe plow whereby the disk may be arranged to throw dirt either to theright or to the left.

3. In a turning plow,^the combination, of a supporting frame, a platformcarried by the rear portion of said frame and having a substantiallysemi-circular longitudinally eX- tending depression, a beam rockablymount ed in said depression, a disk carried at the forward end of saidbeam and disposed in an angle to the line of the travel of thesupporting frame, a hand lever connected to said beam for rocking vthebeam to reverse the angle of said disk with respect to the line oftravel of the frame, whereby the disk may be arranged to throw dirteither to the right or to the left.

4:. In a turning plow, the combination, of a supporting frame, aplatform carried by the rear portion of said frame and having asubstantially semi-circular longitudinally extending depression, a beamrockably mounted in said depression, a disk carried at the forward endof said beam and disposed in an angle to the line of travel of thesupporting frame, a hand lever connected to said beam for rocking thebeam to reverse the angle of said disk with respect to the line oftravel of the frame, whereby the disk may be arranged to throw dirteither to the right or to the left standards adjustably carried by saidsupporting frame, supporting wheels carried by the lower ends of saidstandards, and means connecting said standards and said beams foradjusting the elevations of said wheels synchronouly with the reversingof the angle of said disk.

5. In a plow, a supporting structure, a platform carried at the rearthereof, a beam arranged substantially centrally and longitudinally ofthe platform and mounted for oscillating movement, a disk carried bysaid beam and adapted to be reversed when the beam is oscillated, meansfor oscillating said beam, a plate secured to turn with the beam, a pairof links connected to opposite ends of said plate and moving therewith,a pair of parallel shafts arranged at the sides frame, hand levers onsaid shafts for swinging the same, loose connections between said linksand hand levers, connections being madek respectively at opposite sidesof said lastmentioned shafts, arms extending from the forward ends ofsaid shafts, vertically reciprocating standards, links connecting saidstandards with said arm, and wheel mounted on the lower end of saidstandards and adapted to be alternately lifted and lowered when the diskis changed from one to the other position.
